(A) Rheological properties of agarose, agarose-collagen 2 mg/mL, agarose-collagen 4.5 mg/mL, and collagen hydrogels with temperature variation over time. (B) Extracted storage and loss moduli at 37 and 24°C. n = 3 independent replicates, mean ± SD; *p < 0.05, ***p < 0.001; light gray asterisks on bars indicate a statistically significant difference compared to all other hydrogel types at the same temperature.
